Inventor: JOHNSON RAYMOND
IPC: E03D11/16
Filed: 1993-07-05
Abstract: Abstract This invention relates  to plumbing fittings and is concerned particularly with the extension of the water closet outlet.      The discharge end of a water closet outlet better known in the plumbing industry as the Toilet Horn, is manufactured flush with base rim of the water closet.  The discharge end of a water closet (Toilet Horn) is then fitted to the plumbing drainage system by means of a floor flange with wax or sponge rubber gasket.  With two bolts extended up from the floor flange and secured to the water closet with washer and nuts.      This method of sealing a water closet often results in a leakage between the water closet outlet (Toilet Horn)  and the plumbing drainage floor flange.      I have invented a Toilet Horn extender to overcome this problem.  With one end of the Toilet Horn extender attached to the water closet discharge outlet (Toilet Horn) and the other end of the Toilet Horn extender inserted into the plumbing drainage pipe and seal by means of a rubber "O" ring.      It is an object of the present invention to provide a water tight seal between the water outlet and the plumbing drainage line regardless of the difference in the height of the finish floor level and the plumbing drainage floor flange.

Filed: 1992-04-29
Abstract: A portable system for substantially automated monitoring of nerve conduction velocity through the carpal tunnel of a patient includes an electrode supporting structure (10) which supports stimulating (44) and pickup (40) electrodes in a predetermined spatial relationship so as to contact the patient's arm and hand. The electrode supporting structure (10) is a part of a housing which contains stimulating signal generating (42) and response signal processing (28) circuitry, which operates substantially automatically under control of a microprocessor (30). The microprocessor controls generation of stimulating pulses and determines the elapsed time until the occurrence of a predetermined response signal characteristic, such as its peak. Data relating to nerve conduction time or velocity measurements and response signal waveform are stored in a removable memory (34) to permit later analysis and treatment recommendation by a physician. The system is useful for screening large groups of people at remote locations, such as workers at an employer's facilities, for evaluating their median nerve condition and likelyhood of developping carpal tunnel syndrome.

Abstract: SIMULATOR FOR RAILROAD HOT WHEEL DETECTOR                   ABSTRACT OF THE DISCLOSURE    A  simulator  is  provided  for  verifying  the  proper operation of railroad rolling stock hot wheel detectors.  The simulator includes heaters mounted on trucks of a railroad car,  between  the  wheels  and  within  the  profile  of  the thickness of the wheels.   Shock mounts, spring mounts and safety cables are used.  An electromagnet is mounted on the heater to trip a sensor to activate the detector and a sensor on the car is used to determine the ambient temperature. Each heater includes a heater temperature sensor and is maintained  at  a  constant  temperature  above  ambient  to approximate the thermal radiation of a hot wheel.  Each heater is adjusted to direct heat horizontally outwardly from the truck to permit a hot wheel detector adjacent to and outside of the rail to detect a hot wheel.  The car has two trucks with one heater on each side of each truck.  One heater on each side simulates a temperature approximately equal to a hot wheel.   The other heater on each side simulates a lower temperature and should not be detected as a hot wheel.  The simulator can be integrated with a hot bearing simulator system.

IPC: B65G23/06
Filed: 1994-03-02
Abstract: Split sprocket wheels having interlocking tabs for forming a sprocket wheel assembly that is easy to install on and remove from a drive or idler shaft of a belt or chain conveyor. The invention provides thin, durable sprocket wheels split into at least two sectorial sections along seams extending from a central bore to an outer engagement surface.  Mating tabs and receptacles at the edges of adjacent sectorial sections interlock the adjacent sections radially and circumferentially. Holes in the vicinity of the mating tabs and receptacles of adjacent interlocked sections admit locking means for holding the sectorial sections together in axial compression. The sprocket wheels can be ganged together at selected positions along a shaft with their bores in coaxial alignment by means of spacers interconnecting consecutive sprocket wheels along the shaft. Sprocket wheels can be disengaged for removal from the shaft by loosening the locking means and sliding one section axially with respect to the other section by a distance as little as the thickness of the thin sprocket wheel. Then each section can be removed from the shaft without the need for dismounting the shaft from the conveyor system.

Patent CA-2120678-A1 (CA)
Inventor: FISCHER ADDISON M
IPC: G06F21/00
Filed: 1994-04-06
Abstract: The disclosed methodology permits an insecure computing system to safely perform high security electronic financial transactions. The present invention permits the hash of a file to be taken on an incremental basis. It permits any part of the file to be changed while allowing a new aggregate hash to be computed based on the revised file portion and the prior total hash. The aggregate hash is readily updatable with each record revision without having to recompute the hash of the entire file in accordance with conventional techniques. These objectives using two functions. The first function is an effective one-way hash function "H" for which it is computationally impossible to find two data values that hash to the same result. The second function is a commutative and associative function "F" (and inverse "Finv") and provider a mechanism for combining the aggregate hash and the hash of updated records.      Examples of these latter functions include exclusive OR ("XOR"), and arithmetic addition. The methodology involves combining the hash of each file record and the hash of an identification of the record (i.e., a record number or key). These hashes are combined using a function ("F") whereby individual records may be extracted using the inverse of that function (Finv). In this fashion, an individual record may be extracted from the aggregate hash and updated. With each update, the file hash as computed according to this invention is preferably also written after being encrypted under a key known only to the valid user, or if it is digitally signed by the valid user or if it is held in a tamper resistant storage. Each record is represented by its identification hashed together with its data content. All such record are added together to provide a highly secure integrity check. This aggregate hash reflects the entire database such that the tampering (or rearranging) of any data record is revealed by the use of the record identifier (i.e., record number) in the hash calculation due to its impact on the aggregate hash (e.g., the sum).
